Description

Technical Field

[0001] This utility model belongs to the field of greenhouse frame technology, and in particular relates to a wind and snow resistant reinforced greenhouse frame structure that can be quickly disassembled and assembled. Background Technology

[0002] In agricultural production, greenhouses serve as core facilities for regulating crop growth environments and protecting crops from adverse weather conditions. Their skeletal structure is a crucial foundation for supporting the overall shape of the greenhouse and ensuring its stable operation. With the diversification of modern agricultural planting models, farmers have increasingly flexible requirements for greenhouse applications. Greenhouses not only need to adapt to different regional terrains and planting scales for different crops, but also need to withstand the impact of severe weather such as winter snow accumulation and seasonal strong winds on the greenhouse structure. Therefore, the ease of assembly and disassembly, dimensional adaptability, and wind and snow resistance of the greenhouse frame have become core indicators for evaluating its performance.

[0003] However, existing greenhouse frame structures still have many shortcomings in practical applications that make them difficult to meet the actual needs of farmers:

[0004] First, the assembly and disassembly processes are cumbersome and inconvenient. Traditional greenhouse frames rely heavily on welding or multiple sets of bolts for fixing. Farmers need to carry various specialized tools such as wrenches and welding machines when assembling or disassembling them, which not only increases labor and time costs, but also easily causes bolt stripping, component deformation, and other damage, making it difficult to reuse parts. Second, the size adaptability is poor. The longitudinal beams of existing greenhouses are mostly designed with fixed lengths. When farmers need to adjust the length and width of the greenhouse according to the planting area, they must customize longitudinal beam components of the corresponding size, which not only prolongs the preparation cycle, but also increases equipment investment costs and cannot quickly respond to diverse planting needs. Third, the resistance to wind and snow is weak. Most traditional greenhouse frames rely on simple connections between support columns and crossbeams for structural support, lacking specialized reinforcing components. Under the vertical pressure of accumulated snow or the lateral impact of strong winds, crossbeams are prone to bending, support columns to tilt, or even the whole structure to collapse. This will not only damage the crops inside the greenhouse, but may also bring additional maintenance and economic losses to farmers. In view of this, we propose a wind and snow resistant reinforced greenhouse frame structure that can be quickly assembled and disassembled. Utility Model Content

[0005] The purpose of this invention is to provide a wind and snow resistant reinforced greenhouse frame structure that can be quickly disassembled and assembled, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly assembled and disassembled, comprising:

[0007] Multiple sets of support column mechanisms, and the multiple sets of support column mechanisms are distributed in a shape like the Chinese character 'Ri'. The support column mechanism consists of support legs, connecting block one, connecting block two, and positioning sleeves.

[0009] Preferably, the crossbeam mechanism includes:

[0010] Two longitudinal beams, which are symmetrically arranged. A sliding hole is opened on the side wall of the adjacent side of the longitudinal beam. A connecting sleeve is sleeved at the connection of the two longitudinal beams. An anti-detachment block matching the sliding hole is arranged inside the connecting sleeve, and the connecting sleeve is in sliding cooperation with the sliding hole.

[0011] Preferably, a threaded mounting hole is opened on the side wall of the connecting block two, a clamping block is threadedly connected inside the threaded mounting hole, and one end of the longitudinal beam facing the connecting block two is fixed to the clamping block through a bolt.

[0012] Preferably, the structural strengthening member includes:

[0013] A strengthening plate, which is plug-in installed between two adjacent vertically distributed longitudinal beams. A card slot matching the strengthening plate is opened on the side wall of the longitudinal beam. The two sides of the strengthening plate are respectively in plug-in cooperation with the card slots on the side walls of the two longitudinal beams. A through hole is opened in the middle of the strengthening plate, and a bolt is plug-in installed in the through hole on the strengthening plate. The strengthening plate is fixed to the connecting block two through the bolt.

[0014] Preferably, a bolt is threadedly connected to the circumferential outer wall of the positioning sleeve, and the positioning sleeve is fixed to the foot of the arched beam through the bolt.

[0015] Preferably, the fixing mechanism includes:

[0016] A sliding groove is formed within a connecting block 1. An elliptical block is rotatably mounted in the center of the sliding groove. Sliding plates that slide and engage with the sliding groove are symmetrically arranged on both sides of the elliptical block. Return springs are fixedly installed between the two sliding plates and near the four corners. A rotating rod is inserted into the outside of the connecting block 1, and the other end of the rotating rod extends into the sliding groove and is coaxially connected with the elliptical block. An insert block is fixed on the outer side of the sliding plate. An insertion hole is formed at the foot of the connecting block 2. One end of the insertion hole passes through the sliding groove and extends to the outside to engage with the corresponding insertion hole. A limiting component is provided on the outer wall of the connecting block 1 to limit the rotation direction of the rotating rod.

[0017] Preferably, the limiting component includes:

[0018] A fixing block is fixed to the outer wall of the connecting block and is coaxial with the rotating rod. The fixing block has a pin hole, and a pin is inserted into the pin hole. The circumferential side wall of the rotating rod has a positioning cross hole that matches the pin, and the pin is inserted into the positioning cross hole.

[0019] Preferably, the knob portion of the rotary rod located on the outside is provided with anti-slip texture.

[0020] The beneficial effects of this utility model are:

[0021] 1. This quick-assembly and reassembly wind and snow-resistant reinforced greenhouse frame structure solves the pain points of traditional greenhouse frame assembly and disassembly relying on complex tools and cumbersome procedures. It achieves quick assembly and disassembly without special tools, and the parts are undamaged after disassembly and can be reused, which greatly improves the efficiency of assembly and disassembly and the utilization rate of parts. The structure is achieved through the threaded engagement between the support legs and the threaded protrusions in the support column mechanism, the plug engagement between the connecting block two and the connecting block one, and the fixing mechanism composed of the rotating rod, elliptical block, sliding plate and plug block, as well as the limiting component composed of fixing block, pin hole, plug pin and positioning cross hole.

[0022] 2. This quick-assembly and reassembly wind and snow resistant reinforced greenhouse frame structure achieves fine-tuning of the longitudinal beam position through the sliding fit between the two longitudinal beams and the connecting sleeve, combined with the threaded connection between the locking block and the threaded mounting hole. This solves the pain point of traditional longitudinal beams having fixed dimensions and being unable to adapt to the construction needs of greenhouses of different lengths and widths. The overall length of the crossbeam mechanism can be flexibly adjusted without the need for custom-made special longitudinal beams, improving the versatility of parts and the flexibility of greenhouse construction.

[0023] 3. This quick-assembly and reassembly wind and snow resistant reinforced greenhouse frame structure forms a triangular support structure through the slotted connection of the reinforcing plate and the longitudinal beam, which is then fixed with two bolts to the connecting block. Combined with the arched design of the arched beam, it solves the pain points of traditional greenhouse frames that lack effective reinforcement structure, have weak wind and snow resistance, and are prone to bending and collapse. It greatly enhances the connection strength between the crossbeam mechanism and the support column mechanism, disperses the pressure of snow accumulation and the impact of lateral wind force, ensures the overall structural stability of the greenhouse frame, and improves wind and snow resistance performance.

[0033] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.

[0034] In this application, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated device, component or part must have a specific orientation, or be constructed and operated in a specific orientation.

[0035] Embodiment 1:

[0036] This embodiment provides a quickly disassemblable and anti-wind-and-snow reinforced greenhouse frame structure, including:

[0037] Multiple groups of support column mechanisms, which are distributed in a "day" shape. The support column mechanism consists of a support leg 1, a first connecting block 2, a second connecting block 4, and a positioning sleeve 8. A threaded convex block 3 is fixedly installed on the lower surface of the first connecting block 2. The support leg 1 is in threaded cooperation with the threaded convex block 3. The second connecting block 4 is in plug-in cooperation with the first connecting block 2. The positioning sleeve 8 is fixedly installed on the upper surface of the second connecting block 4. A crossbeam mechanism is arranged between adjacent two groups of support column mechanisms. An arched beam 9 is inserted and installed between two positioning sleeves 8 in the same row of the same column;

[0038] A fixing mechanism for fixing the second connecting block 4 is arranged in the first connecting block 2. A structural strengthening member is arranged between adjacent two crossbeam mechanisms.

[0039] Among them, the multiple groups of support column mechanisms are distributed in a "day" shape, which can make the overall force of the greenhouse frame uniform, avoid damage in the snow and wind load due to concentrated force in a local area, and provide a stable basic support for the subsequent installation of the crossbeam mechanism and the structural strengthening member; the support leg 1 and the threaded convex block 3 adopt threaded cooperation, which can not only quickly adjust the overall height of the support column mechanism by rotating the support leg 1 to meet the installation requirements of different terrains, but also directly unscrew the support leg 1 during disassembly to achieve rapid separation of parts without the aid of complex tools; the plug-in cooperation mode of the second connecting block 4 and the first connecting block 2, compared with traditional welding or multi-bolt fixation, greatly shortens the assembly time of the support column mechanism, and can quickly achieve the stable connection of the second connecting block 4 and the first connecting block 2 in cooperation with the fixing mechanism in the first connecting block 2, preventing the second connecting block 4 from disengaging from the first connecting block 2 under the impact of snow and wind;

[0040] An arched beam 9 is installed between two positioning sleeves 8 in the same horizontal row. As an arched structural component of the greenhouse roof, the arched beam 9's design can effectively disperse the pressure of snow accumulation at the top, while reducing the impact of lateral wind on the greenhouse, thus improving its resistance to wind and snow. The insertion method facilitates the quick installation and disassembly of the arched beam 9, and no damage to other structures is required during later maintenance or replacement. The structural reinforcements set between adjacent beam mechanisms can further enhance the connection strength between beam mechanisms, forming a three-dimensional load-bearing frame, preventing the beam mechanisms from bending or shifting under the action of wind and snow, and ensuring the stability of the overall structure of the greenhouse frame.

[0041] Example 2:

[0042] This embodiment provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly assembled and disassembled. In addition to the technical solutions of the above embodiments, it also has the following technical features, including a crossbeam mechanism:

[0043] Two longitudinal beams 5 are arranged symmetrically. A sliding hole 6 is provided on the side wall of an adjacent side of the longitudinal beams 5. A connecting sleeve 7 is fitted at the connection of the two longitudinal beams 5. An anti-detachment block matching the sliding hole 6 is provided inside the connecting sleeve 7. The connecting sleeve 7 and the sliding hole 6 are slidably engaged. The other end of the longitudinal beam 5 is connected to the connecting block 4 on the corresponding side.

[0044] The two longitudinal beams 5 are symmetrically arranged and connected by a connecting sleeve 7. The anti-detachment block inside the connecting sleeve 7 slides with the sliding hole 6 on the side wall of the longitudinal beam 5, so that the two longitudinal beams 5 can slide flexibly along the axial direction of the connecting sleeve 7. By adjusting the relative position of the two longitudinal beams 5 in the connecting sleeve 7, the overall length of the crossbeam mechanism can be changed, thereby adapting to the construction needs of greenhouses with different lengths and widths. There is no need to customize special longitudinal beams 5 for specific greenhouse sizes, which improves the versatility of parts and the flexibility of greenhouse construction.

[0045] The anti-detachment block effectively prevents the longitudinal beam 5 from detaching from the connecting sleeve 7 during sliding adjustment or under wind and snow loads, ensuring the stability of the crossbeam mechanism connection and preventing the partial collapse of the greenhouse structure due to the detachment of the longitudinal beam 5. The other end of the longitudinal beam 5 is connected to the connecting block 4 on the corresponding side, which can transfer the force of the crossbeam mechanism to the support column mechanism, forming a complete force transmission path, so that the entire greenhouse frame can jointly bear the wind and snow load, reducing the stress on a single structural component. At the same time, this connection method provides a basis for the rapid disassembly and assembly of the crossbeam mechanism and the support column mechanism, facilitating the disassembly, relocation, or expansion of the greenhouse in the future.

[0046] Example 3:

[0047] This embodiment provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly disassembled and assembled. In addition to the technical solution of the above embodiment, it also has the following technical features: the side wall of the connecting block 2 4 is provided with a threaded mounting hole 21, and a locking block 22 is threadedly connected in the threaded mounting hole 21. The end of the longitudinal beam 5 facing the connecting block 2 4 is fixed to the locking block 22 by bolts.

[0048] Among them, the side wall of the connecting block 24 is provided with a threaded mounting hole 21, and the locking block 22 is threadedly connected to the threaded mounting hole 21. The mounting position of the locking block 22 on the connecting block 24 can be quickly adjusted by rotating the locking block 22, so as to accurately align with the mounting hole of the longitudinal beam 5 facing the end of the connecting block 24, avoid the installation misalignment problem caused by the machining error of the parts, and improve the installation efficiency.

[0049] The end of the longitudinal beam 5 facing the connecting block 2 4 is fixed to the locking block 22 by bolts. Compared with directly opening mounting holes on the connecting block 2 4 to fix the longitudinal beam 5, the setting of the locking block 22 can protect the main structure of the connecting block 2 4, avoid damage to the connecting block 2 4 caused by repeated disassembly and assembly, and extend the service life of the connecting block 2 4.

[0050] The bolt fixing method not only ensures the stability of the connection between the longitudinal beam 5 and the connecting block 2 4, but also effectively transmits the lateral wind and snow load on the crossbeam mechanism, prevents relative displacement between the longitudinal beam 5 and the connecting block 2 4, and allows for quick separation of the longitudinal beam 5 and the connecting block 2 4 by unscrewing the bolts during disassembly. The operation is simple and the parts can be reused.

[0051] In addition, the threaded engagement between the locking block 22 and the threaded mounting hole 21 allows for fine adjustment of the extension length of the locking block 22 according to the installation requirements of the longitudinal beam 5, further enhancing the flexibility of the crossbeam mechanism installation, ensuring that the crossbeam mechanisms at different positions can maintain the same horizontal height, and enhancing the overall structural regularity and stability of the greenhouse frame.

[0052] Example 4:

[0053] This embodiment provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly assembled and disassembled. In addition to the technical solutions of the above embodiments, it also has the following technical features, and the structural reinforcement components include:

[0054] The reinforcing plate 24 is inserted and installed between two adjacent vertically distributed longitudinal beams 5. The side wall of the longitudinal beam 5 has a slot 23 that matches the reinforcing plate 24. The two sides of the reinforcing plate 24 are respectively inserted and engaged with the slots 23 on the side wall of the two longitudinal beams 5. The middle part of the reinforcing plate 24 has a through hole, and bolts are inserted and installed in the through hole of the reinforcing plate 24. The reinforcing plate 24 is fixed to the connecting block 2 4 by bolts.

[0055] Among them, the reinforcing plate 24, as a structural reinforcing component, is installed between two adjacent vertically distributed longitudinal beams 5 using a plug-in method. The slot 23 on the side wall of the longitudinal beam 5 provides precise positioning for the reinforcing plate 24, ensuring that the reinforcing plate 24 can be quickly connected to the longitudinal beam 5, reducing the positioning adjustment time during the installation process.

[0056] The two sides of the reinforcing plate 24 are inserted into the slot 23, which can limit the longitudinal beam 5 in both the horizontal and vertical directions to prevent the longitudinal beam 5 from shifting or bending under the action of wind and snow load. At the same time, it forms a triangular support structure, which greatly improves the connection strength between the crossbeam mechanism by utilizing the stability principle of triangle, effectively disperses the wind and snow impact force on the longitudinal beam 5, and avoids damage to a single longitudinal beam 5 due to excessive force.

[0057] A through hole is opened in the middle of the reinforcing plate 24 and it is fixed to the connecting block 2 4 with bolts. This can transfer the force of the reinforcing plate 24 to the support column mechanism, forming a multiple force transmission path of "beam mechanism - structural reinforcement - support column mechanism", which further enhances the overall load-bearing capacity of the greenhouse frame. This structural design ensures the wind and snow resistance reinforcement effect while taking into account the need for quick disassembly and assembly. When disassembling, the reinforcing plate 24 can be pulled out from the slot 23 simply by unscrewing the bolts. The parts are undamaged, which is convenient for later storage, transportation and reuse.

[0058] Example 5:

[0059] This embodiment provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly disassembled and assembled. In addition to the technical solutions of the above embodiments, it also has the following technical features: the outer circumferential wall of the positioning sleeve 8 is threaded with bolts, and the positioning sleeve 8 is fixed to the foot of the arch beam 9 by bolts.

[0060] Among them, the positioning sleeve 8 is fixedly installed on the upper surface of the connecting block 2 4, providing a stable support foundation for the installation of the arch beam 9. The arch beam 9 is installed by inserting the two positioning sleeves 8 in the same horizontal row, which can quickly complete the construction of the arch structure on the top of the greenhouse without complicated splicing procedures.

[0061] The threaded bolts on the outer circumference of the positioning sleeve 8 are fixed to the foot of the arch beam 9 by the bolts. This can convert the axial pressure of the bolts into a clamping force on the foot of the arch beam 9, preventing the arch beam 9 from coming out of the positioning sleeve 8 or rotating under the action of wind and snow, and ensuring the stability of the arch structure.

[0062] The arched beam 9 with its arched design can evenly distribute the weight of the snow on the top to the positioning sleeves 8 and the support column mechanism on both sides, preventing the snow from accumulating on the top and causing excessive local pressure. At the same time, the arched structure can also reduce the resistance of lateral wind force and reduce the impact of wind on the top of the greenhouse.

[0063] During installation, simply insert the foot of the arch beam 9 into the positioning sleeve 8 and then tighten the bolts. When disassembling, simply unscrew the bolts to pull out the arch beam 9. The operation is simple and quick, and the bolt fixing method will not cause structural damage to the positioning sleeve 8 and the arch beam 9. It is conducive to the reuse of parts and reduces the cost of greenhouse construction and maintenance.

[0064] Example 6:

[0065] This embodiment provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly assembled and disassembled. In addition to the technical solutions of the above embodiments, it also has the following technical features, including a fixing mechanism:

[0066] A sliding groove 10 is formed inside the connecting block 1 2. An elliptical block 11 is rotatably mounted in the middle of the sliding groove 10. Sliding plates 12 that slide and cooperate with the sliding groove 10 are symmetrically arranged on both sides of the elliptical block 11. A return spring 13 is fixedly installed between the two sliding plates 12 and near the four corners. A rotating rod 14 is inserted into the connecting block 1 2, and the other end of the rotating rod 14 extends into the sliding groove 10 and is coaxially connected with the elliptical block 11. An insert block 15 is fixed on the side of the sliding plate 12 facing outward. An insertion hole 16 is formed at the foot of the connecting block 2 4. One end of the insertion hole 16 passes through the sliding groove 10 and extends to the outside to be inserted and cooperated with the corresponding insertion hole 16. A limiting component is provided on the outer wall of the connecting block 1 2 to limit the rotation direction of the rotating rod 14.

[0067] The sliding groove 10 inside the connecting block 12 provides installation space for the various parts of the fixing mechanism. The elliptical block 11 is rotatably installed in the middle of the sliding groove 10. The rotating rod 14 extends into the sliding groove 10 and is coaxially connected to the elliptical block 11. The elliptical block 11 can be rotated by rotating the rotating rod 14 outside the connecting block 12. There is no need to go deep into the connecting block 12 to operate, which improves the ease of operation of the fixing mechanism.

[0068] The elliptical block 11 is symmetrically provided with sliding plates 12 that slide in cooperation with the sliding groove 10 on both sides. When the elliptical block 11 rotates, it can squeeze the sliding plate 12 through its elliptical structure, so that the sliding plate 12 slides outward along the axial direction of the sliding groove 10, thereby driving the insert 15 on the outer side of the sliding plate 12 to be inserted into the insertion hole 16 at the foot of the connecting block 2 4, so as to realize the quick fixation of the connecting block 2 4 and the connecting block 1 2. The entire fixation process only requires rotating the rotating rod 14, without the need for additional tools, which greatly shortens the installation time.

[0069] A reset spring 13 is installed between the two sliding plates 12 near the four corners. The reset spring 13 adopts a spring structure. When the elliptical block 11 rotates in the opposite direction, it can pull the sliding plate 12 to slide inward, so that the plug 15 can be dislodged from the plug hole 16, thereby realizing the quick separation of the connecting block 2 4 and the connecting block 1 2, which is convenient for disassembly.

[0070] The insertion of the plug 15 into the socket 16 can limit the connection block 4 in the radial direction, preventing the connection block 4 from shaking inside the connection block 2. Combined with the limiting component to limit the rotation direction of the rotating rod 14, it can prevent the rotating rod 14 from rotating on its own under wind and snow vibration, causing the plug 15 to come out, ensuring the stability of the fixing mechanism, and thus ensuring the overall stability of the support column mechanism.

[0071] Example 7:

[0072] This embodiment provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly assembled and disassembled. In addition to the technical solutions of the above embodiments, it also has the following technical features, including limiting components:

[0073] The fixing block 17 is fixed to the outer wall of the connecting block 12 and is coaxial with the rotating rod 14. The fixing block 17 has a pin hole 18, and a pin 19 is inserted into the pin hole 18. The circumferential side wall of the rotating rod 14 has a positioning cross hole 20 that matches the pin 19. The pin 19 is inserted into the positioning cross hole 20.

[0074] Among them, the fixing block 17 is fixed to the outer wall of the connecting block 12 and is coaxially set with the rotating rod 14, ensuring that the pin hole 18 on the fixing block 17 and the positioning cross hole 20 on the rotating rod 14 can be accurately aligned, providing a positioning basis for the insertion and engagement of the pin 19.

[0075] A pin 19 is inserted into the pin hole 18. The pin 19 is compatible with the positioning cross hole 20 on the rotating rod 14. When the rotating rod 14 is rotated to the fixed position where the plug 15 is fully inserted into the insertion hole 16, the pin hole 18 and the positioning cross hole 20 are just aligned. At this time, inserting the pin 19 into the pin hole 18 and the positioning cross hole 20 can limit the rotation direction of the rotating rod 14 and prevent the rotating rod 14 from rotating on its own when the greenhouse is subjected to wind and snow vibrations, causing the plug 15 to fall out of the insertion hole 16. This ensures that the fixing mechanism does not fail to fix the connecting block 2 4. The positioning cross hole 20 adopts a cross-shaped structure. Similarly, when the rotating rod 14 is rotated until the plug 15 is separated from the insertion hole 16, the positioning cross hole 20 is still aligned with the pin hole 18. After inserting the pin 19, the stability of the rotation direction of the rotating rod 14 can still be guaranteed.

[0076] The pin 19 adopts a plug-in method, and installation and disassembly do not require tools. It can be installed and removed manually, which is simple to operate and will not damage the fixing block 17 and the rotating rod 14. In addition, the coaxial design of the fixing block 17 and the rotating rod 14 can ensure that the limiting force of the pin 19 on the rotating rod 14 is evenly distributed, avoiding damage to the rotating rod 14 due to excessive local force, and extending the service life of the limiting component. At the same time, this structural design is compatible with the quick assembly and disassembly characteristics of the fixing mechanism and does not affect the overall assembly and disassembly efficiency of the support column mechanism.

[0077] Example 8:

[0078] This embodiment provides a wind and snow resistant reinforced greenhouse frame structure that can be quickly disassembled and assembled. In addition to the technical solutions of the above embodiments, it also has the following technical features: the knob part of the rotating rod 14 located on the outside is provided with anti-slip texture.

[0079] The knob part of the rotating rod 14 located on the outside is provided with anti-slip texture, which can increase the friction between the hand and the knob, and prevent slippage caused by wet hands, wearing gloves or excessive force during installation or disassembly. This ensures that the operator can rotate the rotating rod 14 stably, and improves the safety and reliability of the operation.

[0080] Especially during the construction or maintenance of greenhouses in winter, the ambient temperature is low, and the operator's hands are prone to stiffness or sweating. The anti-slip texture can effectively improve the contact effect between the hand and the knob, reduce the error rate, and ensure that the rotary lever 14 can be smoothly rotated to the target position, thereby ensuring that the fixing or unlocking action of the fixing mechanism is accurately completed.

[0081] Meanwhile, the anti-slip texture design requires no additional parts, does not affect the overall structure and size of the rotating rod 14, and will not interfere with the cooperation between the rotating rod 14 and other parts. While improving the ease of operation, it also takes into account the simplicity and practicality of the structure, which is in line with the overall design concept of quick assembly and disassembly of the greenhouse frame and convenient operation.

[0082] Working principle:

[0083] When assembling this quick-assembly and quick-disassembly wind and snow-resistant reinforced greenhouse frame structure, the support column mechanism is first constructed: the support leg 1 is connected to the threaded protrusion 3 on the lower surface of the connecting block 1 2 through a threaded engagement. By rotating the support leg 1, the overall height of the support column mechanism can be quickly adjusted to adapt to different installation terrains. Then, the connecting block 2 4 is inserted into the connecting block 1 2. The rotating rod 14 with anti-slip texture on the outside of the connecting block 1 2 is rotated. The rotating rod 14 drives the coaxial elliptical block 11 in the sliding groove 10 to rotate. The elliptical block 11, through its elliptical structure, presses the sliding plates 12 on both sides that slide in cooperation with the sliding groove 10, causing the sliding plates 12 to slide outward and drive the insert block 15 to be inserted into the insertion hole 16 at the foot of the connecting block 2 4, thus achieving the initial fixation of the connecting block 2 4 and the connecting block 1 2. Then, the pin 19 is inserted into the pin hole 18 on the fixing block 17. At this time, the pin 19 cooperates with the positioning cross hole 20 to limit the rotation direction of the rotating rod 14, ensuring the stability of the support column mechanism. This process does not require complicated tools and achieves quick assembly.

[0084] Next, the crossbeam mechanism is installed: according to the length and width requirements of the greenhouse, the positions of the two symmetrically arranged longitudinal beams 5 in the connecting sleeve 7 are slid to adjust the overall length of the crossbeam mechanism; then, through the threaded mounting hole 21 on the side wall of the connecting block 2 4, the end of the longitudinal beam 5 facing the connecting block 2 4 is fixed to the locking block 22 with bolts, thus completing the connection between the crossbeam mechanism and the support column mechanism, meeting the installation requirements of greenhouses of different sizes.

[0085] Next, install the structural reinforcement components: insert the reinforcement plate 24 into the slots 23 of two adjacent vertically distributed longitudinal beams 5, and then insert bolts through the through holes in the middle of the reinforcement plate 24 to fix the reinforcement plate 24 and the connecting block 2 4. The reinforcement plate 24, the longitudinal beam 5, and the connecting block 2 4 form a triangular support structure, which greatly improves the connection strength between the beam mechanism and the support column mechanism and enhances the overall wind and snow resistance.

[0086] Finally, the top structure is constructed: the feet of the arched beam 9 are inserted into the two positioning sleeves 8 in the same horizontal row, and the bolts on the outer circumference of the positioning sleeves 8 are tightened to fix the arched beam 9 to the positioning sleeves 8. The arched structure of the arched beam 9 can disperse the pressure of the snow accumulation at the top and reduce the impact of lateral wind force, further improving the wind and snow resistance performance.

[0087] During disassembly, the operation is reversed: first, unscrew the bolts to remove the arch beam 9, pull out the pin 19, and then rotate the rotating rod 14 in the opposite direction. The sliding plate 12 slides inward under the tension of the return spring 13, and the insert block 15 disengages from the insertion hole 16, thus separating the connecting block 2 4 from the connecting block 1 2. Then, unscrew the bolts to remove the reinforcing plate 24, separate the longitudinal beam 5 from the locking block 22, and finally unscrew the support leg 1 to complete the disassembly of each part, achieving quick disassembly and reuse of parts.
